I have about 8 months of trail riding on an MCFK steerer, so far with no real problems at all. I have a light weight top cover and bung in the steerer which adds about 20g, but at least gives some option for adjusting the headset when out on the bike. The tightening torque for the fork clamps on the steerer is lower than on the Cannondale steerer, so I think that makes it coming out of adjustment somewhat more likely. For a race though you could clearly remove it.
thank you. hm. unless i go with a really
light stem, the need for a cap/expander reduces the benefit.
cannondale system = 79 + 171 = 250g
mcfk + F109 + cap/expander = 79 + 113 + 20 = 212g
any really light stems that work with 31.8 bars and are good for real-world use? the F109 seems quite sturdy and sensibly priced. extralite has the UltraStem OC @ 85g (http://www.extralite.com/Products/UltraStem%20OC.htm
), which is more appealing from a weight perspective.....but too light for real MTB use?
i plan to use either Enve sweep (700mm) or MCFK flat (also 700mm) bars -- both 31.8 diameter. I ordered the MCFK and now admit that I wonder if they would be a problem in a crash. (I read some language from Extralite that 25.4 bars are stronger, and their carbon+alu bars are the best for normal use + an occasional crash (http://www.extralite.com/Products/handlebars%20standard.htm
); however, they do not make their 25.4 bars in a width I prefer.)
any comments on the stem? should i worry at all about the MCFK flat 31.8 bar? i KNOW the Enve sweep bar is OK.
